· Succulent woody shrubs 1 to 3 cm high with milky sap. Mature stem cylindrical in shape with 3 to 6 ridges; younger branches green with 3 to 5 ridges. The projection of the ridges armed with a pair of 2 to 3 mm long spines.
· Leaves: few, borne on the ridges, succulent, obovate to oblanceolate to spathulate in shape. Apex obtuse with a small pointed projection, base gradually narrowing downward, sessile. Deciduous.
· Flowers: male flower with only 1 stamen, filament short; female flower situated alone at the center of the cyathium, protruding beyond the involucre. Styles 3, not joined to each other, each style forking towards the tip. Yellowish-green, monoecious inflorescence, composed of several staminate (male) flowers and one pistillate (female) flower borne on a green, hemispherical involucre. The whole cuplike cymose inflorescence is called cyathium.
· Fruits: glabrous, smooth, about 1 cm in diameter.
– From the latex, study isolated three new triterpenes, euphol-3-O-cinnamate, antiquol A and antiquol B, with known triterpenes, euphol, 24-methylenecycloartanol and cycloeucalenol; together with a nonacosene, sitosterol and p-acetoxyphnol.
· Collected the whole year round.
· Remove cortex after harvest, cut into sections, roast in frying pan till brownish-yellow.
· Bitter tasting, cooling effect.
· Stomachic, antifebrile, antiphlogistic, anti-infectious, antidermatosis.
· Acute gastroenteritis: use 3 to 6 gms dried materials in decoction.
· Malignant furuncle and carbuncle infections: use pounded fresh stem (quantity sufficient) and apply as poultice.
· Scabies, various dermatoses: apply sap over afflicted areas.
· In India, Juice of plant used for chest pains and constipation. Latex applied to boils for early suppuration and healing. Bark is used as purgative. Latex used for klling wound maggots. Saline extract used as antibiotic.
• Milk of E. antiquorum is applied near to eyes for cattle to treat conjunctivitis and corneal opacities.
• Milk is applied to the neck and joints of cattle to treat black quarter.
• In Northeast India, one of the Euphorbia species used to ward off evil spirits.
• This drug is toxic. Frying neutralizes the toxin, after which it can be taken orally. However, excessive dosage may still cause diarrhea.
• The milky sap or latex, which is also poisonous, must not come in contact with the eyes; skin contact with this sap may cause skin inflammation. Take caution too that this is not administered to pregnant patients.
• Anti-Epstein Barr Virus Activation: Study yielded three triterpene alcohols from the latex. Some compounds showed potent inhibitory effects on Epstein-Barr virus early antigen activation.
• Hepatoprotective / Antioxideant: Study of aqueous extract of the aerial parts of Euphorbia antiquorum showed significant antioxidant activity and also significant dose-dependent hepatoprotection, effects comparable to Silymarin and Sodium metabisulphite. The results helps justify its traditional use for treating jaundice.
• Insecticidal: Study of the insecticidal properties of EA showed the components were best extracted by xylene. The xylene-latex extract was highly toxic to soft bodied insects / spiders. On storage, both the xylene-latex extract and the n-hexane fraction were still highly stable with only a 3 % decline of activity after one year.
